Product Description

Marine butterfly brass check valve
Product Description
Butterfly valve, also called the flap valve is a kind of simple structure of the regulator, it can be used for low pressure pipeline medium of switch control which refers to the closed butterfly valve (valve clack or butterfly plate) is a disc, the valve can reach open and close by rotating around the valve, it can be used to control air, water, vapor, mud, all kinds of corrosive medium, oil, liquid metal and radioactive medium such as various types of fluid flow.  Its function in the line is mainly to cut off and throttle.  Butterfly valve opening and closing is a disc-shaped butterfly plate, the body rotatesaround its own axis, so as to achieve the aim of opening and closing or adjust.
Structure features
1. Butterfly valve has a simple structure, small volume, light weight and material consumption economic, small installation size,  quick switch,  90 reciprocating rotary  and low driving torque, etc, used for truncation, connecting and regulating medium in pipe, has good flow control characteristics and close the sealing performance
2. Butterfly valves can transport mud which accumulated the least liquid in the apertures, under low pressure, it can achieve good sealing performance. The regulating performance is good.
3. The streamline design of the butterfly plate, make the loss of the fluid resistance is small which is a kind of energy-saving products
4. Valve stem for stem structure, through conditioning processing, it has the good comprehensive mechanical properties and anti-corrosion characteristic, when the butterfly valve opening and closing the valve stem make rotation movement up and down and run, not only the valve stem packing is not easy to damage, but also possess reliable sealing performance. With the butterfly plate fixed cone pin, overhanging end to prevent rushed out of the design, in order to avoid broking out of the valve in the stem and disc joint.
5. The connection including the flange connection, clash connection, butt welding and lugs on the clip
6. With manual drive form, worm gear transmission, electric pneumatic, hydraulic electric hydraulic linkage actuator, which can realize remote control and automation
